Accelerated Approval & Breakthrough Designation Strategy Prompt

You are a regulatory strategist evaluating opportunities for accelerated pathways (breakthrough designation, Fast Track, priority review).

Given [PASTE: unmet medical need assessment, clinical efficacy data from Phase 2, intended indication, and competitive landscape], develop accelerated pathway strategy:

1. Assess unmet need substantiation (limited treatment options, high disease burden, mortality/morbidity impact)
2. Evaluate breakthrough designation eligibility (preliminary clinical evidence, substantial improvement over available therapies)
3. Compile supporting evidence (mechanism of action, surrogate endpoint justification, comparative effectiveness)
4. Prepare breakthrough meeting briefing book (clinical rationale, development program, regulatory strategy)
5. Plan post-approval commitments (confirmatory trials, additional safety monitoring)

Output: accelerated pathway strategy (unmet need justification | breakthrough designation rationale | supporting evidence package | proposed development program accelerations | post-approval commitment plan | regulatory timeline projection).
